FILLING CLAMPING AND PAR/TING MEANS FOR LOOMS.

Specification of Letters Patent.

Patented Oct. '7, 1919.

Application filed September 16, 1918. Serial No. 254,237.

T 0 all whom it may concern:

Be it known that I, UBALD HEBERT, a citizen of the United States,residing at Manchester, county of Hillsborough, State of New Hampshire,have invented an Improvement in Filling Clamping and Parting Means forLooms, of which the following description, in connection with theaccompanying drawing, is a specification, like characters on the drawingrepresenting like parts.

This invention relates to looms of the type wherein the running fillingis replenished prior to complete exhaustion and in which a shuttlefeeler is employed to restrain the operation of the replenishingmechanism in case of animproperly boxed shuttle, and in which means areprovided for clamping and parting the filling of the abandoned fillingcarrier, such means being usually supported by, or moving with, theshuttle feeler.

The invention is more particularly concerned with means for effectingthe closing action of the filling clampingand parting means.

The object of the invention is to provide a mechanism which shall besimple in construction, easy to adjust, subject to as little wear aspossible, and which shall efiect the closing operation, preferably by ayielding action, of the filling clamping and parting means only when theshuttle containing the exhausted or substantially exhausted fillingcarrier is properly boxed at the transfer end of the loom.

These and other features of the invention will appear more fully fromthe accompanying description and drawings and will be particularlypointed out in the claims.

The invention in the preferred construction disclosed is shown asembodied in aloom of the well known Northrop type having a rectilinearlymovable shuttle feeler of the type disclosed in the patent to'Davis No.1,091,813 granted March 31, 191 But it is obvious that the invention inits broader aspects may be embodied in various specific forms ofconstruction depending upon the character of filling replenishing loomto which it may be applied.

In the drawings,

Figure 1 is a transverse section of a portion of the automatic fillingreplenishing loom having one embodiment of the present invention appliedthereto, the lay being shown in full lines on back center and in dottedlines on front center, and only those parts being shown which arenecessary to an understanding of the invention;

Fig. at is a detail in front elevation of a portion of the lay showingthe bunter, positioner and trip mechanism; Fig. 5 is a detail view on alarger scale n side elevation showing the actuator and 1ts support, theView being taken looking toward the left in Fig. 3;

Fig. 6 is a top plan view partially in horizontal cross-section of theconstruction shown in Fig. 5.

The lay 1, transferrer 2 to transfer the fresh filling carriers, or inthis case the bobbins 3, from the magazine or hopper 4 containing thesupply of fresh filling carriers to the lay as into the shuttle 5 whenin the box at the transfer end of the loom, the controlling rock shaft 6journaled on the front of the breast beam 7, are all of a constructionfamiliar in the Northrop type of automatic filling replenishing loom,the construction and operation of which is well known to those skilledin this art.

The remaining mechanism, except that particularly involved in thisinvention is fully illustrated and described in the beforementionedpatent to Davis and therefore needs no extended description.

In the construction illustrated the transferrer 2 is pivotally mountedon a hub 8 in the hopper stand or other fixed portion'of the loom and isprovided with a depending arm 9 carrying a rectilinearly movable dog 10.A bunter 11 is rigidly secured to a shaft 12 journaled in a bearingblock 13 mounted on the face of the lay 1. WVhen after the call forfilling replenishment the shaft 12 is rotated to elevate the-hunter 11and the lay beats up the hunter striking the dog 10 effects theactuation of the transferrer to transfer a fresh filling carrier 3 fromthe hopper 4; to the lay, all in a familiar manner.

ried by a supporting arm 15 which depends .Thi's'guide bar 17 is rigidlysupported by means of the set screws 18 in a bearing socket 19 formed inone arm 20 of a supporting bracket 21 fitting over and locked to thetransferrer hub 8 by a set screw 22.

The shuttle feeler is actuated by a bell crank lever 23 fulcrumed at Menthe upper end of a second arm 25 projecting upwardly from the supportingbracket 21. One arm 26 of this bell crank lever is loosely connectedtoan arm 27 laterally projecting from the sleeve 16 of the shuttlefeeler support while the other arm 28 has a pin and slot connectionwith. a link 29 connected at itslower end to an arm 30 extendingrearwardly from the controlling rock shaft 6. A helical spring 31secured at one end to the bell crank lever 23 and at the opposite end tothe upper end of the arm 25 functions to swing the bell crank lever 23clockwise and thus to move the shuttle feeler support with the shuttlefeeler thereo11 rearwardly while at the same time permitt ng the shuttlefeeler support to have a swinging or rotary movement on its anis.Normally the parts stand in the positlon shown in Fig. '1. Upon the callfor filling replenishment the controlling rock shaft 6 is rotated toelevate the arm 30 against the action of the spring 32 and thus raisethe link 29 and permit the spring 31 to function.

This construction and operation is all more fully set forth in thebefore mentioned patrent to Davis.

an actuator supporting bracket 40 is secured The filling clamping andparting means are preferably movable with and preferably carried by theshuttle feeler. These means include the fixed clamping blade 33 the Ifixed cutting blade 34 the movable clampment this car contacting with apin 39 at.

the end of the guide bar 17 swings the movable blades to open positionas shown in Fig. 2. i

A movable and preferably a yielding actuatoris provided for effectingthe closing of the filling clamping andparting means and this actuatorispreferably supported from the loom frame independently of the shuttle.feeler and is given its actuating movement by means carried by andmovable on the lay.

In the preferred construction illustrated to. some fixed part of theloom such for example as a .rearwardly extcndlng pro ection 41 of thefecler supporting bracket 21 and isshown as heldin place by a bolt 42.

The bracket 40 is preferably ribbed at 43 to fit into acorrespondinglygrooved portion of the projection 41 and thus prevent xthe bracket from turning. A stub shaft 44 is rigidly mounted by means ofthe set screw 45 in a horizontally projecting hub 46 of the actuatorbracket 40. The actuator 47 is journaled on the stub shaft 44 andcomprises a depending arm 48 having a lateral projection 49 at its lowerend and a rearwardly projecting arm 50 which is preferably constitutedas a thin spring metal blade clamped in place-by a set screw 51. .The

actuator is maintained with the arm or blade 50 in elevated position bya helical spring 52 surrounding the stub shaft in a pocket in thebracket 40 and fastened'at one end to the bracket and at the other endto theactuator. The upward movement of the to effect replenishment areeffected by means 7 mounted upon the lay and brought into operativeposition by the shuttle feeler when the shuttle feeler has indicatedthat the shuttle is properly boxed at the transfer end of the loom afterthe call for filling replenishment.

In the construction illustrated the shaft 12- journaled in the bearingblock 13 onthe face of the lay has secured thereto in addition to thehunter 11 a positioner 55 and a trip 56. The hunter llcoiiperates withthe dog 10 on the transferrer as already described; the positioner 55cooperates with a heelv 57 depending from the shuttle feeler; and thetrip '56 cooperates with the lateral projection 49 of the depending arm48 of the actuator. A, helical spring 58 on the shaft 12. engaging theposition'er 55 at one end and the bearing block at the otherv end actsnormally to swing the shaft clockwise until the adjustable stop 59carried by the hunter contacts with the bearing block and when the partsare in this position there w1ll be no contact of the hunter, positioneror trip with the dog, heel or projection when the lay beats up andconsequently no wear of the parts. V

The parts are so constructed'and adjusted that when the filling in. therunningfilling carrier in the shuttle has become exhausted orexhaustedto a predetermined degree and that fact has been indicated bythe usual indicating means the controlling rock shaft 6 will be rotatedagainst the action of the spring 32. Thereupon the shuttle feeler withthe fillingclamping and parting means carried thereonis moved rearwardlyunder the action of the spring 31 until the end of the, sleeve 16engagesthe pin 39. Asthis movement concludes the pin 39 engaging thetail 38 swings the movable members of the clamping and parting means toopen position. As the lay now beats up with the shuttle containing theexhausted filllng car rier at the transfer end the shuttle feeler 14feels for the shuttle and if the shuttle is improperly boxed so that itpro3ects from the box the shuttle contacts with the shuttle feeler andthe latter is moved forwardly and there is no operation of thetransferrer. If, however, the shuttle is properly boxed as the lay beatsup the shuttle feeler passes the end of the shuttle and the positioner55 comes into contact with the heel 57 of the rearwardly projectedshuttle feeler and rocks the shaft 12 against the action of the spring58 elevating the hunter 11 and trip 56 connected thereto into line withthe dog 10 of the transferrer and the lateral projection 49 of theactuator respectively. As the beat up of the lay continues thepositioner 55 pushes the shuttle feeler forwardly and the hunter 11engaging the dog 10 actuates the transferrer in the usual manner totransfer a fresh filling carrier from the hopper into the shuttle andeject the exhausted filling carrier therefrom and the trip 56 cominginto contact with the projection 49 of the actuator swings the actuatorabout its pivot 44 bringing the spring blade arm 50 into contact withthe top edge of the movable cutting blade 86 and swinging this blade andthe connected movable clamping blade downwardly thus clamping and part:ing the filling extending from the abandoned filling carrier through theeye of the shuttle to the fell of the cloth.- Thereafter the parts underthe action of the springs 32, 52 and 58 return to their normal positionsas lllustrated in Fig. 1.
